Five Ways to Improve Your Photo
Each mode targets a different type of image problem. Pick the one that fits your photo.
Auto Enhance
The safest starting point. Applies a calibrated mix of contrast (+18%), sharpness (+60%), saturation (+12%) and brightness (+4%) for a universally improved result on almost any photo.
Sharpen
Uses an unsharp mask (radius 1.5, strength 180%) to recover edge definition. Ideal for photos that look slightly soft from camera shake, phone compression, or digital zoom.
Denoise
OpenCV's Non-Local Means (NLM) algorithm compares pixel patches across the whole image to remove grain intelligently. Falls back to Pillow's median filter if OpenCV is unavailable.
Boost Colors
Saturation is lifted by 55% and contrast by 22%, turning flat or washed-out photos into vivid, eye-catching images. Great for travel, food, and product photography.
Restore (CLAHE)
Contrast Limited Adaptive Histogram Equalization divides the image into small tiles and equalizes each independently. Brings out hidden low-light detail in old, faded, or underexposed photos.
Zero Cost
All five modes run entirely on the server using open-source Python libraries. No calls to OpenAI, Replicate, Hugging Face or any paid API. No credits are ever deducted.
Frequently Asked Questions
Photo Enhancement Workflow
Pick the enhancement based on the actual problem in the photo.
Sharpen carefully
Sharpening helps edges and text, but too much creates halos. Use it lightly for portraits and more strongly for screenshots.
Denoise before upscaling
Noise becomes more visible when an image is enlarged. Clean it first, then upscale if you need more resolution.
Compress last
Enhance from the best source, then use compression only after the final image looks right.
Match the fix to the image
Dark photos
Improve exposure and contrast first. Sharpen only after the image has enough light and shape.
Soft screenshots
Prioritize readable text and crisp interface edges. Avoid heavy denoise because it can blur small lettering.
Old photos
Denoise gently, then make small contrast and color adjustments so faces still look natural.
Before you publish
Protect product accuracy
Keep color, material and finish realistic. Over-saturated edits can make a listing feel less trustworthy.
Use the cleanest source
Enhancement cannot fully fix an extremely small or motion-blurred file. If size is the issue, move to the AI Image Upscaler.
Keep the set consistent
Use similar enhancement strength across thumbnails, product photos and article visuals so the page feels polished.
Avoid over-editing
Watch for halos
Too much sharpening can create bright outlines around hair, product edges and text. If edges look harsh, crunchy or outlined, use a lighter enhancement pass.
Do not erase texture
Denoise should reduce grain without making skin, fabric, food or product materials look plastic. Keep enough natural detail for the image to feel real and trustworthy.
Export once at the end
Finish exposure, noise, sharpness and size first. Then export and compress the final image so quality does not degrade through repeated saves or format changes.
Use enhancement for real publishing problems
Listings
Clean product photos enough to show shape, material and labels clearly without making the item look different from reality.
Articles
Improve hero and inline images so they look sharp in the content column, then resize and compress them for faster loading.
Profiles
Keep skin and hair natural. A light correction usually looks more credible than aggressive smoothing or high-contrast sharpening.
For website images, enhance first, then use the Background Remover or Image Compressor as needed for faster, cleaner publishing.
